FURNACE.

To all whom it may concern Y Be it known that I, ARTHUR SCHIMMEL, a citizen of the United States, residing at Evansville, in the county .of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Furnaces;

and I do declarethe following to be a full clear, and exact description of the lnventlon,

such as will enable others skilled in the art to which it appertains to make and use the same. o

My invention relates to improvements 1n furnaces, and more particularly to those of the hot air'type, the main object of the in-.

vention being to improve upon the construc-.' tion of devices of this class to such an extent as to provide a heater from which hot air may be directed into a single room for led to a number of rooms, by a novel arrangement of parts.

With this general object in view, the invention resides incertain novel features of construction and in unique combinations of parts to'be hereinafter fully described and claimed, the descriptive matter being. supplemented by the accompanying drawings wherein:

Figure 1 is a front elevation of a furnace constructed in accordance with my invention; Fig. 2 is a vertical sectional view as seen on the plane designated by the line f uppermost section 12 of the inner shell is 22 of Fig. 1; Figs. 3, 4, 5 and 6 are horizontal sectionsnas viewed upon the planes designated respectively by the lines 3 3,

41-4, 55 and 6-6 of Fig. 2; Fig. 7 is aperspective view pf one of the rin -'like secs tions of one of the shells; Fig. 8 1s a detail top plan view illustrating a modifiedform ofconstruction to be described; Fi 9.i sa, detail vertical section taken on the line 9-.-9.

of Fig. 8.; Fig. 10 is a' bottom plan view of one of the cover plates disclosed "in Figs. 8

and 9.

In these drawings which constitute a part of the application and in which similar reference characters designate corresponding parts throughout the several views, the unmeral l designates a base frame which-prefe'rably comprises a. circular ring 2 having an upstanding flange, and if plurality of inwardly extending arms 3 upon which the bottom of 'the'ash pit 4 of the furnaceproper rests, the latter being designated broadly. by the reference'numeral 5. The" furnace 5 may be of any preferred formation although the design disclosed is preferable, the device Specification of Letter: latent.

being shown as provided with a cast metal passageway 6 through which fuel maybe fed to the fire-box 7, while the ash pit4 doors 9 and proper 5, is an inner-shell 11 which is composed of a number of sheet metal sections such as that disclosed at v12 in Fig. 7, said sections being capable of bein spread out fiat for purposes of packing an transportation, but normally assuming substantially the. contour seen in the aforesaid figure, one

end of each section beingprovided with an appropriate crimp 13 which constitutes a seat for the other end, while both ends are provided with apertured Years 15 through which bolts 16 are metal sections 12 and each having an external central rib 17 which is disposed between the adjacent edges of such sections, is a plurality of cast metal rings 18, the lowermost of which is supported rigidly by appropriate braces 19 from the'base 1.

ly' equipped with passed (see Figs. 3, 4, 5- and 6). j

assageways '6' and 8 being As" most clearly shown infFig. 2, the i ositioned a considerable distance above the rnace proper, while the section between the latter and said uppermost section is gradually decreased in size from its lower v toits' upper end being frusto cone-shaped. Fitting snugly within, or snugly surrounding the upper end'of the uppermost section 12, as 'theca'se may be, i s an annular flange 20 which depends from an appropriate grating 21 adapted to be placed over an opening in a floor 22 above the furnace room, whereby heat rising from the furnace{ may be utilized for heating the room or. rooms directly above the aforesaid furnace room. Also dependin from thegrating 21, but

s' aced outwar y from and surroundin the tion being {therefore deemed unnecessary,

except that it may be stated thatthe lowerabove the furnace proper.

most section 12 and the section immediately above the same, are provided with apertured ears 14" through which appropriate fasteners 15 are passed, said fasteners being here shown as extended through additional ears 14* on the opposite edges of the upper and lower cast metal front plates 24 and 25 to which the doors 9 and 10 are respectively hinged, and through which the passageways 6 and 8 open.

In addition to the shell and jacket above described, an insulating lining 26 of black iron or other appropriate material is provided, such lining being here shown as composed of a number of ring-like sections whose upper and lower edges are received in hooloshaped keepers 27 formed on the upper and lower edge portions of the rings 18 at the inner sides of the latter. This insulating means is provided in order that cold air may flow downwardly between the shell and the jacket as indicated by the arrows in Fig. 2 and may then pass upwardly within the inner shell to be heated by the furnace proper therein, yet that such air may not be noticeably heated in its downward course. By this means, loss of heat into the furnace room is prevented.

Standing upright and extending diametrically across the frusto cone-shaped section of the lining 26 is a one-piece sheet metal partition 28 whose opposite ends are inclined and. bent laterally to form attaching flanges 28*"- contacting with said section and secured thereto. Disposed one pair on eachside of the partition 28 are two pairs of radially positioned upright partitions 28", each pair of such partitions being formed by bending a single sheet of metal into V-shape as shown clearly in Figs. 3 and 4;. The corner of each of these V-shaped formations is flattened as shown at 28, such flattenedportion contacting with opposite sides of the partition 28 at the center thereof and being secured thereto by boltsnor the like 28, the latter passing through said portions and through said partition as shown. The outer ends of the partitions 28 are inclined and bent laterally to form attaching flanges 28 contacting with and secured to the aforesaid frusto cone-shaped Section of the lining 26.

his construction, although simple and inexpensive, will be efiicient and durable. By .securing the ends of the partitions to the lining, expansion and contraction of said partitions under changes in temperature will be readily allowed since said lining is spaced from the inner shell and mayi thus yield for this purpose. The formations just described constitute a plurality of segmental heat pockets having constantly open unobstructed lower ends disposed immediately Usually, the upper ends of such pockets will be equipped with =vertically swinging top plates 29 disposed between the upper edges of adjacent partitions and preferably mounted upon horizontal rods 30 whose opposite ends are journaled in such edges. If such plates be provided, pulleys or other appropriate guides 31 will be placed at substantially the points of intersection of the several partitions, and chains or other cable members 32 will be secured to the inner ends of the plates 29, will betrained upwardly over the guides or pulleys, and will be passed through openings in the numerous shells to the exterior of the casing as shown in Fig. 1, whereby any or all of the plates 29 may be raised or lowered at will.

In some cases, the removablepivotally mounted top plates 29 may be replaced by rigidly supported removable plates such as those disclosed at 30 in Figs. 8, 9 and 10, such plates being provided with downwardly opening crimps 3O receiving therein the upper edges of the several partitions, and being secured in position by bolts or the like 30.

Whether the plates 30 or 30 be provided, when disposed to horizontal position, such plates are designed to normally prevent the escape of heated air through the upper ends of the dome-like pockets, said air however, being designed to pass from the furnace through a number which extend outwardly one from each pocket and which are adapted to be connected with other appropriate pipes which may lead to suitable registers or the like disposed in the several rooms in the building to be heated, more particularly in the rooms on the upper floors, since the lower floor will be effectively heated by radiating heat from the furnace proper, which will rise through the grating 21. The amount of heat rising ,through such grating, may be increased at will by removing the top plates 30 or 30, but it will be evident that as long as such plates are disposed horizontally as seen at the left of Fig. 2, an equal amount of heat will flow from each pocket to a correspondmg room. 7

The furnace proper 5 is shown in the present embodiment of the invention as provided with an updraft outlet pipe 34 and a downdraft outlet 34, both of these pipes being preferable, for reasons well known to those skilled in the art to which the invention relates. The two pipes 34 and 34 pass loosely through alined openings in the shell and jacket and in the lining of said shell, and are surrounded by collars 35 and 35 which abut the exterior of the jacket. To retain these collars in position, the construction seen more particularly inFigs. 5 and 6 is provided. This construction comprises a pair of hook shanks 36 whiclr are formed integrally with opposite-edges of the opening in the jacket through which theipipe 34 passes, and' an additional pair of such shanks 36 which are formed integrally with the opening in the jacket receiving th downdraft pipe 34.

The shanks 36 and 36 extend respectively to points betweenthe collar 35 and the pipe 34 and between the collar 35* and the pipe 34, the free ends of the shanks 36 and 36 being bent laterally to rovide respectively hook bills 37 and 37 w ichreceive therein the inner edges of the collars 35 and 35.

By this means, the collars are effectively tails, it isjobvious that I need not be limited thereto otherwise than to the extent to which the appended claims restrict me.

I claim:

1. In combination, a furnace proper, a substantially cylindrical shell surrounding the same, rising therefrom, and having an,

open upper end provided with a horizontal grating, a plurality of upright, radially 10- cated partitions in the shell between the furnace proper and the grating, said partitions.

meetin each other at a central point and extendlng to the shell to provide a plurality of segmental heat pockets, the latter having constantly open unobstructed lower ends disposed immediately above the furnace proper, removable segmental top plates for closing or opening the upper ends of said pockets to either allow or obstruct the passage of heat therefrom through the grat ing, and independent heat outlets leading from the pockets beyond the exterior of the shell.

2. In combination, an upright shell comprising a body portion of cylindricalformation, a frusto cone-shaped-flsection rising therefrom, and a cylindrical upper section rising from said frusto cone-shaped section, a grate at the upper end of said upper section, an upstanding one piece sheet metal partition extending diametrically across the aforesaid frusto cone-shaped section of the shell and having inclined ends bent laterally and forming attaching flanges, two pairs of radially located partitions disposed one pair on each side of the first named partition,

each of said pairs being formed of a single sheet of metal bent into the form of a V with its ends inclined and bent laterally to form attaching flanges, the corners of the V-shaped formations being flattened and disposed in contact with opposite sides of said first named partition at the center thereof, bolts passed through said'flattened corners and through the intervening partition, removable segmental cover plates posltioned horizontally and filling the spaces between the upper edges of the numerous partitions, whereby to form therewith heat pockets, independent hot air outlets leading from such pockets beyond the exterior of the shell, means for admitting air into the lower end of said 'shell, and a furnace in said shell below the partitions.

3. In combination, an upright shell comprising a body portion of cylindrical formation, a frusto cone-shaped Section rising.

therefrom, and a cylindrical upper section rising from said frusto cone-shaped section, a grate at the upper end of said upper section, a lining in the shell including avfrusto cone-shaped section disposed within and spaced from the frusto cone-shaped section of said shell, an upstanding one-piece sheet metal partition extending diametrically across said section of the lining andchaving inclined ends bent laterally andforming attaching flanges secured to such section, two pairs of radially located partitions disposed one pair on each side of the first named partition, each of said pairs being formed of a single sheet of metal bent into the form of a V with its ends inclined and bent laterally to form attaching flanges secured to the aforesaid lining section, the corners of the V-shaped formations being flattened and disposed in contact with opposite sides of said first named partition at the center thereof, bolts passed through said flattened corners and through the intervening partition, removable segmental cover plates posilower end of said shell, and a furnace in said shell below the partitions.

In testimony whereof I havehereunto set my' hand in presence of two subscribing witnesses.
